[SOLVED] Is there a method to tween only the position of a part/union?

I'm creating an animated sliding gate. But whenever I open the gate, the gate tweens to its position, but the orientation gets affected as well (i.e rotates 90° during the animation)

Is there a method to only tween the position, completely ignoring orientation?

Here is my code I am working with:

local TweenService = game:GetService("TweenService")

local gatemain = script.Parent:WaitForChild("GateMain")
local info = TweenInfo.new(3.4,Enum.EasingStyle.Quint,Enum.EasingDirection.In,0,false,0)

local gatemainopen = {CFrame = CFrame.new(-499.15, 30.5, -63.35)}
local gatemainclose = {CFrame = CFrame.new(-517.15, 30.5, -63.35)}

local tweengatemainopen = TweenService:Create(gatemain,info,gatemainopen)
local tweengatemainclose = TweenService:Create(gatemain,info,gatemainclose)

local dooropen = false

function onTouch(hit)
	local Gatekey = hit:FindFirstChild("GateKey")
	if Gatekey then
		if dooropen == false then
			tweengatemainopen:Play()
			dooropen = true
		else
			tweengatemainclose:Play()
			dooropen = false
		end
	end
end

script.Parent.GateMain.Touched:Connect(onTouch)
